目的 比较超声造影和MRI对乳腺 占位病变的鉴别诊断效果。方法 选取我 院2012年5月-2015年4月78例乳腺占位性 病变患者，分别对其手术前进行的超声 造影检查和MRI检查结果进行统计分析， 对比两者的鉴别诊断效果。其中对超声造 影结果进行定性分析，对比超声造影各 项指标间的差异。结果 (1)在超声造影 定性检查中，40例恶性患者中均匀强化 (+)18例，均匀强化(-)22例，灌注缺损 (+)29例，灌注缺损(-)11例，周边放射性 血管(+)26例，周边放射性血管(-)14例， 强化后病灶范围增大(+)24例，强化后病 灶范围增大(-)16例；38例良性患者中均 匀强化(+)33例，均匀强化(-)5例，灌注 缺损(+)6例，灌注缺损(-)32例，周边放 射性血管(+)8例，周边放射性血管(-)30 例，强化后病灶范围增大(+)11例，强化 后病灶范围增大(-)27例。均匀性、灌注 缺损、周边有无放射状血管、强化后病灶 范围扩大在良性和恶性乳腺占位性病变之 间的差异都具有统计学意义。(2)在MRI检 查中，39例良性患者中，渐进型有20例， 平台型有17例，廓清型有2例；39例恶性 患者中，渐进型有1例，平台型有14例， 廓清型有24例。由此可知，渐进型和廓清 型在良性和恶性之间的差异具有统计学意 义，平台型在良性和恶性之间的差异无统 计学意义。(3)超声造影诊断结果中4例恶 性患者为误诊，4例良性患者为误诊；MRI 诊断结果中3例恶性患者为误诊，3例良性 患者为误诊。超声造影和MRI的诊断效果 无统计学意义。结论 超声造影和MRI对乳 腺占位性病变的鉴别诊断效果具有良好的 一致性，都在临床诊断中有很好的应用价 值。

Objective To compare contrast-enhanced ultrasound and MRI in the differential diagnosis of breast lesions results. Methods 78 patients with space-occupying lesions were selected in the breast in our hospital from May 2012 to April 2015, they were performed before surgery and MRI results were statistically analyzed to compare the effect of both the differential diagnosis. In which the results of the ultrasound contrast qualitative of contrast-enhanced ultrasound contrast the differences between the indicators. Results (1) qualitative CEUS examination, 40 cases of malignancy in patients with homogeneous enhancement (+) 18 cases, homogeneous enhancement (-) 22 cases, perfusion defect (+) 29 cases, perfusion defect (-) 11 cases, the surrounding Radioactive vessels (+) 26 cases of peripheral vascular radioactivity (-) 14 cases, after strengthening the scope of the lesions increased (+) 24 cases, after strengthening the range of lesions increased (-) 16 cases; homogeneous enhancement in 38 cases of patients with benign (+) 33 cases, homogeneous enhancement (-) 5 cases, perfusion defect (+) 6 cases, perfusion defect (-) 32 cases of peripheral vascular radioactivity (+) 8 cases, peripheral vascular radioactivity (-) 30 cases, strengthening the range of lesions after increase (+) 11 cases, strengthened to increase the range of lesions (-) 27 cases. Uniformity, perfusion defect, whether a neighboring radial artery lesions expand the scope of the differences between benign and malignant breast lesions were statistically significant after strengthening.(2)MRI examination, 39 cases of benign patients, there are 20 cases of progressive type, platform type, 17 cases of type 2 patients clearance; 39 cases of malignant patients, there was one case of a progressive type, platform type there were 14 cases, there were 24 cases of clearance type. It can be seen, the difference between benign and malignant progressive and statistically significant clearance were typed, platform type differences between benign and malignant not statistically significa(3) CEUS diagnosis of four cases of malignant misdiagnosed patients, 4 cases of benign patients were misdiagnosed. MRI diagnosis in three cases of malignant were misdiagnosed patients, three cases of benign patients were misdiagnosed. The effect of ultrasound diagnostic imaging and MRI are not statistically significant. Conclusion Ultrasound imaging and breast MRI lesions in the differential diagnosis effect with good consistency, all have very good value in clinical diagnosis.
